Solid Cleansing Compositions and Methods for the Same

Abstract

Solid cleansing compositions and methods for the same are disclosed herein. The solid cleansing composition may include a cleansing component and one or more whitening agents. The one or more whitening agents may include one or more of a metal oxide, a clay, a coloring agent, or combinations thereof. The solid cleansing composition may have a whiteness, as measured via a Hunter Whiteness Index (L) of from about 60 to about 90.

1 . A solid cleansing composition, comprising:
 a cleansing component; and   one or more whitening agents, wherein the whitening agents comprise one or more of a metal oxide, a clay, a coloring agent, or a combination thereof,   wherein the solid cleansing composition comprises a whiteness, as measured via a Hunter Whiteness Index (L) of from about 60 to about 90.   
     
     
         2 . The solid cleansing composition of  claim 1 , wherein the whitening agents comprise the metal oxide. 
     
     
         3 . The solid cleansing composition of  claim 1 , wherein the metal oxide comprises zinc oxide (ZnO). 
     
     
         4 . The solid cleansing composition of  claim 1 , wherein the metal oxide is substantially free of titanium dioxide. 
     
     
         5 . The solid cleansing composition of  claim 1 , wherein the one or more whitening agents comprise the clay. 
     
     
         6 . The solid cleansing composition of  claim 5 , wherein the clay comprises one or more of bentonite, kaolin, kaolinite, calcined kaolin, metakaolin, hydrous kandite clay, halloysite or ball clay, smectite, illite, chlorite, hormite, beidelite, sepiolite, alunite, hydrotalcite, nontronite, hectorite, attapulgite, pimelite, muscovite, willemseite, minnesotaite, antigorite, amesite, china clay, halloysite, or a combination thereof. 
     
     
         7 . The solid cleansing composition of  claim 6 , wherein the clay comprises bentonite. 
     
     
         8 . The solid cleansing composition of  claim 6 , wherein the clay comprises calcined kaolin clay. 
     
     
         9 . The solid cleansing composition of  claim 1 , wherein the coloring agent comprises one or more of a dye, a pigment, or a combination combinations thereof. 
     
     
         10 . The solid cleansing composition of  claim 9 , wherein the coloring agent comprises the pigment. 
     
     
         11 . The solid cleansing composition of  claim 10 , wherein the pigment comprises a blue pigment. 
     
     
         12 . The solid cleansing composition of  claim 1 , wherein the one or more whitening agents comprise the metal oxide, the clay, and the coloring agent. 
     
     
         13 . The solid cleansing composition of  claim 1 , wherein the solid cleansing composition comprises a whiteness, as measured via a Hunter Whiteness Index (L) of from about 80 to about 90. 
     
     
         14 . The solid cleansing composition of  claim 1 , wherein the solid cleansing composition comprises a refractive index of from about 1.0 to about 3.0. 
     
     
         15 . A method for preparing the solid cleansing composition of  claim 1 , the method comprising contacting the cleansing component and the one or more whitening agents with one another. 
     
     
         16 . A method for treating or preventing damage to skin, the method comprising contacting the solid cleansing composition of  claim 1  with the skin. 
     
     
         17 . The method of  claim 16 , wherein the solid cleansing composition prevents lipid peroxidation of the skin. 
     
     
         18 . A method for preventing antibacterial growth on skin, the method comprising contacting the solid cleansing composition of  claim 1  with the skin. 
     
     
         19 . The method of  claim 18 , wherein the antibacterial growth comprises  E. coli  growth. 
     
     
         20 . The method of  claim 18 , wherein the antibacterial growth comprises  S. aureus  growth.
